The hydrostatic pressure experienced by a scuba diver at 40 meters below the surface of the ocean is _ kPag. (Rounded-off to the nearest whole number.)

(a) Find the pressure at the bottom of a 20 meter deep lake ( water density =1000Kg/m**3, atmospheric pressure P_0=1.013* 10**5 Pa (Pascal). (b) If, on a cold day, the lake is covered with a 0.5 meter thick layer of ice (density of ice=917Kg/m**3), find the pressure at the bottom of the lake. A.) (a)P1 = 2.973 x 105 Pa;         (b)P2= 3.018 x 105 Pa B.) (a)P1 = 12.44 x 105 Pa;         (b)P2= 31.35 x 105 Pa C.) (a)P1 = 392.1 x 105 Pa;        (b)P2= 112.4 x 105 Pa D.) (a)P1 = 22.66 x 105 Pa;         (b)P2= 981.0 x 105 Pa

The atmospheric pressure on an object decreases as altitude increases. If a is the height (in km) above sea level, then the pressure P(a) (in mmHg) is approximated by P(a)=760e-0.13a. Determine the atmospheric pressure at 7.176 km. Round to the nearest whole unit.

Please help me: Part (a)  If the pressure is measured in compartment C at PC = 1.69 atm and compartment A is open to the atmosphere, what is the height difference H2, in centimeters, in the manometer between B and C?  Part (b)  What is the pressure in compartment D, in atm?  Part (c)  If we were to replace compartment C and the manometers around it with a single manometer that went right from compartments B to D, what would the height difference be in this new manometer?

Consider the barometer in the figure and calculate the ambient pressure in kPa if h = 3.3 cm, h2 = 54 %3D cm, and the fluid density is 8,575 kg/m3. %3D Po h2 Po kPa %3D

Water has a density of 1000 kgm/m^3and seawater has SG of 1.024 and gravitational acceleration at 0m above sea level is g = 9.81 m/s^2. How many meters deep should a diver go in the seawater to experience an absolute pressure twice as much as standard atmospheric pressure?

By definition, pressure is equal to the force exerted per unit area or P =  F A . Suppose that you place a 22 kg block on the a table.(a) If the bottom surface of the block has an area of 0.44 m2. What is the pressure caused by the block as it sits on the table? (Hint: You will need to find the weight of the block in order to know the force exerted. Use 10 m/s2 for gravity.)P = _______ Pa(b) How would your answer to part (a) change if the are of the block is 0.22 m2?P = ______ Pa

Short Finned Pilot Whale can dive to depths of 1.1 kilometers. What is the total pressure they experience at this depth? (take: p = 1020 kg/m3 and 105 N/m2 = 1 ATM, g=9.81m/s2.)

The deepest part of a swimming pool is 4.9 m below the surface of water. If the atmospheric pressure is 100 kPa, what is the absolute pressure at the deepest part of the swimming pool? Use 997 kg/m3 for the density of the water and g = 9.8 m/s2 for the acceleration due to gravity.  __?____ unit of kPa

The container shown is filled with a mystery liquid with density 15,000 kg/m3. It is open to atmosphere on the left and closed on the right. What is the pressure at point A, in kPa (kiloPascal)? 1.0 atm = 1.00 × 105 Pa = 100 kPa, and g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
